GLOBE-VALVE- SPEGIFIGATION forming part of Letters Patent No. 791,256,dated May 30, 1905.

Application filed February 17, 1904. Serial No. 194,081.

To all whom it may 0071102771 Be it known that I, CLARENCE DURRANT,acitizen of the United States, residing at Marine City, in the county ofSt. Clair and State of Michigan, have invented a new and usefulGlobe-Valve, of which the followingis a specification.

My invention relates to valves, and especially to the class known asglobe-valves, and has for its objects to produce. a comparatively simpleinexpensive device of this character in which the valve may be readilyoper' 'ated and moved freely to and from its seat oppositely-disposedinlet and outlet ports 2 3 and upon its interior with a division-web orpartition 4, arranged between said ports and constituting a Valve-seatinto which is tapped the lower end of a tubular valve-guide 5, the seatbeing provided around the guide with an inwardly beveled or inclinedseating-face 6, adapted to register with a similarly-beveled face 7,provided on the inner end of a valve 8,movably disposed upon the guidememher 5. This member on which the tubular valve is mounted for freereciprocation and which serves to guide the latter in its movements hasits upper or outer end closed, its inner or seat-engaging end open, andis provided through its sidewall with an opening or passage 9, wherebycommunication is established between the ports 2 and 3 through the saidguide. The upper or outer closed end of the valve 8 is provided with adovetail recess 8*, which extends slightly more than one-half across thevalve and is engaged by a similarly-shaped terminal l0 on the inner cessand the dovetail extension 10 on the,

valve-stem connection of the valve and the stem may readily be effected,and,'further, the valve is caused to travel and be revolved with thestem, thereby to cause it to seat itself true upon the valve-seat.

In practice when. the valve 8 is in closed or seated position itsbeveled end will bear tightly upon the seating-face 6, while the body ofthe valve will inclose the guide member 5, thus forming a closure forthe opening 9 and effectually cutting off communication between theports 2 and 3. When, however, the valve is moved to open position, saidpassage 9 will be uncovered or opened and communication establishedbetween the ports through the tubular member 5. directed to the factthat in practice the valve is free from positive engagement with themember 5 and may therefore move readily on the latter, thus to insurerapid opening or closing of the valve, and, further, that the valve isfixed for rotation with its stem, whereby the valve in moving to openand closed positions will grind the faces 6 and ,7 one upon the other,and thus maintaina tight joint.

From the foregoing it is apparent that I produce a simple inexpensivedevice which is admirably adapted for the attainment of the ends inview; but it is to be understood that I do not limit myself to theprecise details herein set forth, as minor changes may be made thereinwithout departing from the spirit of the invention.

Having thus described the invention, what is claimed is The combinationwith a casing having inlet and outlet ports and a web or partitionbetween the ports, of a tubular guide member secured in the partitionand having a lateral Attention is especially passage to establishcommunication between i the ports, the web or partition surrounding theguide member being dished to present a In testimony that I claim theforegoing as valve-seat, a rotary valve housing the guide my own I havehereto affixed my signaturein member and having its lower end beveled t0the presence of two \vltnesses.
